Description:

The L.P. hose is yellow like the main unit to improve visibility. The ideal regulator allows you to breath naturally while under water as it supplis the needed amount of air at the needed time regardless of the water depth or tank pressure. It is based on this theme that TUSA is aiming for the ideal breathing resistance where the regulator breathes easily but does not supply more than the required amoint of air. TUSA installed the only regulator breathing resistance performance tester (ANSTI MACHINE) in Japan, which is used for the product development and to thoroghly check product performance before shipment.

TUSA conducts ANSTI tests before shipment te ensure users recieve products with the ideal breathing resistance. The breathing resistance deemed ideal by TUSA is represented as a flattend oval in the graph. In other words, the inhale and exhale resistance is balanced and at a low pressure like it is during regular breathing on land. This means this regulator lets you breath as little or as much as you want and with a low resistance. TUSA continuously conducts R&D to approach this ideal value.
